Seastead
A contest that I entered a year ago in which you will design a structure in the middle of the ocean with all the amenities as a small town. The design should be self-sustainable and will have basic and advance facilities that are available to a small town. The rendering style that I use here is digital watercolour.The input files for this contest are available in the contest website which consist of a CAD file and Sketchup file. Images and also sample design are available for reference.
I love entering design contest it not only excercise your design skills but also your presentation and drawing skills.
